Revision Summary:
The Principal Investigator has provided new NPP estimates of better quality in reflecting the NPP gradient from SW to NE in Sweden and Finland. The values of ANPP (anpp, Aboveground NPP (gC/m2/yr)) and TNPP (totnpp, Total NPP (gC/m2/yr)) were updated in the 82 grid cells for Sweden and Finland.
These new NPP estimates are discussed in the published paper:
Zheng, D., S.D. Prince, and T. Hame, 2004. Estimating net primary production of boreal forests in Finland and Sweden from field data and remote sensing. J. of Vegetation Science, 15: 161-170.
Data File Changes:
In the following data files:
NPP_Gridded_3654_cells_R2.csv
NPP_Gridded_2335_unique_cells_R2.csv
these two variables were updated for the 82 grid cells comprising Sweden and Finland.
anpp Aboveground NPP (gC/m2/yr)
totnpp Total NPP (gC/m2/yr)
Data set documentation was updated to reflect the new data file names and to include the Zheng et al. 2004 reference.
